columns MACHINE.

Application filed May 9, 1911.

To all whom it may concern Be it known that I, CARL SOHLEIFER, a subjectof the Emperor of, Austria-Hungary, residing at and Whose post-ofiiceaddress is Perosa, Argentina, Italy, have invented certain new anduseful Improvements in Combing Machines; and I do hereby declare thenature of this invention to be particularly described and ascertained inand by the following specification.

My invention relates to a combing machine for W001, flax and all thelike by which the material to be combed is held by gripping jaws andpresented to the comb, whereupon the resulting combed sliver is seizedby an apparatus for pulling 01f and is drawn out of the opened jaws. Ithas heretofore been the practice to employ in such combing machines twocombs lying in parallel planes, one comb acting upon the sliver whilemoving upward, the other while moving downward. According to myinvention the combs alternately are brought in front of the jaws holdingthe sliver. This is done in such manner, that either the gripping jawsare fixed and the combs are shifted or the combs are fixed and thegripping jaws are shifted. The combs are fiat and of sectional or fanshaped form and they are fixed on a shaft which is arranged sidewise andparallel to the direction in which the sliver is fed and drawn off sothat in combing the sliver, the comb is rotating in a complete circle.To obtain a careful and economical combing out, pairs of picking combsare provided, picking one after the other always on the same place inthe sliver, which is held by the pulling ofi mechanism while thegripping jaws are moving back. A nee- 1 dle plate is arranged on theside of the first picking comb, and is turned to the gripping jaws sothat it enters at the same time into the sliver and holds the shortfiber when the lbatter are no longer supported by the feed Reference isto be had to the accompanying drawings forming a part of thisspecification, in which like characters of reference indicatecorresponding parts in all the views, and in which Figure 1 is afragmentary elevation showingone of the combs arranged to pick thesliver asthe comb ascends. Fig. 2 is a fragmentary elevation showing howthe sliver is picked by a comb as the latter descends.

Fig. 3 is a view somewhat similar to Fig.

2, but showing the'same comb in a little more advanced position. Fig. 4shows the means whereby the sliver is drawn out from the feed-box. Fig.5 is a fragmentary elevation somewhat similar to Fig. 4, but showing thesliver in a position still farther advanced on the feed-box. Fig. 6 is afragmentary elevation showing in detail how the sliver is handled afterleaving the feed-box. Fig. 7 is a fragmentary elevation showing the formof the turning combs and the brushes for taking off the short combedfibers. Fig. 8 is a plan view of the mechanism shown in Fig. 7. Fig. 9shows the various revolving brushes used for removing material from theteeth or the combs. Fig. 10 is a plan view of the whole machine. Fig. 11represents a side elevation, the segmentary combs being left out. Fig.12 illustrates the combing machine seen in the direction of the arrowshown in Fig. 10; where the pulling off-head is not illustrated and thefront swing arms are partly represented in section and Fig. 13 is a planview of the whole machine with only one comb, a simplification of theconstruction according to Fig. 10. o

The new combing machine essentially consists of three parts: the feedinghead I, the segment comb-mechanism II, and the pulling off-head III.Besides an endless conveyor-strap f, the feeding head comprises thefeeding device E, the gripping jaws C D, the two pairsof picking combs LU, L L (Fig. 11). The feeding device, the gripping jaws and the combsare disposed on a swing frame composed of two plates 1 upon which thesaid parts are mounted, the swing arms 3 pivoted to the plates 1 and at2 to the frame and the traverse bar 4 pivoted to the arms 3. The frameis reciprocated by the main shaft h by means of the eccentric 5 androlls 6 so that the swing frame may be moved to and fro in the desiredmanner (Figs. 11 and 12). The feeding device E is composed of a suitablybent base plate E supported by the plates 1 and a movable needle plate Ewhich is attached to the lever arm 8 mounted'on the shaft 7. Under thefeeding device a, plate F of sheet metal is provided, which facilitatesthe conveyance of the combed sliver to the pulling off-device.

The gripping jaws C D suitably disposed upon the swing frame are formedusually by an upper stationary gripping jaw C and a lower movablegripping jaw D carried by the two armed lever 9 mounted to oscillate onthe pivot 10. The rear end of the oscillating lever 9 is pivoted to abar 11, which is provided with a spiral spring and said bar is pivotallyattached at the point 12 to the frame (Figs. 11. and 12). By moving theswing frame 1, 3, 4 forward and back ward the gripping jaw D is openedor closed by the said lever (Fig. 11). The picking combs L L moving andcoacting before the gripping jaws, are fastened to the twoarmedsymmetrical swing levers 13 and 14, mounted on the shaft 15 and providedat their ends with articulated bars 16, the said bars again beingjournaled by angle levers, not shown in the drawings, which carry attheir other ends rolls engaging eccentrics 17 of the main driving shaftit (Fig. 12). By rotation of the eccentrics 17 the picking combs L L areactuated. To the upper picking comb L is fixed a small needle plate M,which retains the short fibers being no longer held by the feedingdevice E during the pulling off-process. The front picking combs L and Lare arranged in a similar manner as the combs L and L The picking combsare cleaned in their upper and lower resting positions by the brushes Oattached to the comb segment plates A and B behind the needles (Figs. 1and In front of. the gripping jaws C, D, the two flat segment combs Aand B are arranged, the comb A being provided with needles or teethdirected upward while the needles or teeth of the comb B are directeddownward (Figs. 1, 8, 10). The comb segment A is keyed upon the shaft R,which carries at its end a bevel gear wheel 18 engaging a bevel gearwheel 19 (Fig. 10), supported by a pivot mounted on the frame.

The bevel gear wheel 19 is in gear with a bevel gear wheel 20, which isloosely mounted on the shaft R and rotating in a direction opposite tothe gear wheel 18. The bevel gear wheel 20 carries an elongated hub inthe form of a sleeve, on which the comb sement B is fixed (Fig. 10).With the bevel gear-Wheel 19 is connected a spur wheel 21, which gearswith a wheel :22 placed upon the main driving shaft in The said shaft isconnected with the driving pulley X. by means of a suitable gearing(Figs. 10 and 12).

The roller brushes N and N rotating on the shaft 23 are adapted to cleanthe flat needle plates attached to the rotating comb segments A and B.The roller brushes deliver the noils to the doffing rollers P and Pprovided with wire hooks. From these rollers the short fibers are drawnoff by the dofiing, knife 9. The dofling roller 1 is driven by the mainshaft h by means of the bevel gear wheels 24, 25, the verticalintermediate shaft 26, the worm 27, and the worm wheel 28 (Fig. 12).-The doffing roller P rotates the other dofl'ing roller P by the gearwheels 29 and 30. The roller brushes i and N are operated by the drivingpulley X by means of an intermediate gearing. The main driving shaft itcarries at the side opposite to the driving means, outside of the frame,a spur wheel 31, meshing with a gear wheel 3:2 which in turn meshes withthe gear wheel 33 placed upon the driving shaft 7 of the pullingoff-head III (Figs. 1012).

The pulling off device G, H consists of an endless leather strap itrunning about the roller H and winding around the lower part of the drumT and the gripping jaw G. The drum T carries on its shaft end a gearwheel 31 which is geared with the gear wheel 87 through the intermediategears 35 and 36. Vith the wheel 37 is connected a ratchet wheel 38, withwhich a pawl 39 at the end of the angle lever 40 engages (Fig. 11). Theangle lever mounted on the pivot 41 is provided at its end with a roll42 engaging an eccentric 323 on the shaft W (Figs. 10 and 11). Byrotating the eccentric the angle lever is oscillated, which causes theforward rotation of the ratchet wheel and the intermittent movement ofthe drum and the leather strap. The gripping jaw G is fixed to a lever44 mounted on the shaft 15; the lever 41 is pivotally connected with alever 48 through a spring bar 46. The lever 48 mounted on the fixedpivot a7 is provided with two rolls 49, which engage eccentrics 50 onthe shaft W so as to impart a swinging motion to the lever 44 andgripping jaw G.

The working of the machine is as follows: When the gripping jaws C, D(Fig. 1) are closed, the sliver is combed out by the comb A, movingupward and passing immediately in front of the gripping jaws. When thecomb A has passed the jaws C, D, the jaws are moved forward, until theycome to the working plane of the comb B (Fig. 2). By this comb thesliver is now combed in a direction (Fig. '3) from above to below,contrary to the movement of comb A. The feed-box E is moved back and isclosed. Thecombs A and B, in their farther movement (Fig. 8) contactslightly with the brushes N N rotating with higher speed than the combsA, B. These brushes take off the noils and impurities and deliver it tothe rollers P and P and to the doffing knife 9, as described before. When the combs A, B have combed the sliver, the gripping jaws C, Dare'further moved forward and opened, so thatthe rear end. of the sliveris released, yet still advanced by the feed-box E against the pullingoff mechanism (Fig. Before the gripping jaws cease to move for ward thethin plate F isadvanced, straightening the combed front side of thesliver and delivering it to the roller H of the pulling off apparatus onwhich is still lying the sliver combed in the preceding working period.As the jaw G is raised and the roller H begins to rotate the sliver ismoved forward. When the gripping jaws G, D have reached the end of theirmovement, the plate F is moved back. The feeding being finished, the jawG of the pulling off mechanism is pressed down and the front side of thesliveris caught (Fig. 5). Now the jaws C, I) move back, and the pickingcombsli and L andalso the needle plate M pick into the sliver, and asthey move back with the gripping aws, they carry away the fibers, whichare not held by the pulling off mechanism, and comb with their bigneedles the fibers, the front ends of which are held by the pulling offmechanism G H. lVhile swinging back farther the liner needle shafts L Lpick alternately into the sliver, and then the shafts move back with thegripping jaws. The needles of these combs progressively increase infineness and of course they comb out the sliver in the best manner. Atthe same time the little needle plate M together with the needle shaft Lhas picked into the sliver and holds the short fibers, which are nolonger caught by the feed-box E (Fig. 6). A short time before theswinging back movement is finished, the gripping jaws are closed. Theneedle shafts L L L L return to their first position, where they arecleaned by the brushes 0 attached to the comb segments A and B (Fig. 1)and the working now is repeated as above described. It is to beunderstood that for combing very long stapled material, the swingingmotion of the gripping jaws and picking combs will have to be increased.To keep the motion in certain limits an arm K may be attached on thesegment as shown in Fig. 7, to pull the sliver through the needle shaftsL at the proper time during the return movement of the gripping jaws C,D. In some instances a single fan shaped comb be employed, as shown inFig. 13. The construotion according to Fig. '13 is a simplificationaccording to Fig. 10, which consists in the following: The comb B andthe bevel gear wheel :20 fixed thereto and which are loosely mounted onthe shaft R are omitted and therefore likewise the shifting mechanism ofthe gripping jaws to this comb. The bevel g'ear wheel 18 is mounted onthe shaft adjacent to the comb A and only one roller brush N (Figs/9 and10) is employed.
